[SOLVED] accessing part of an object???

[n8w]

I am trying to get part of an object into a variable .. but I am not sure how to access it

this doesn't seem to work??

print $obj->results['shortUrl']; // 12345

 

how can I do this?

 

$myvar="http://bit.ly/e4miJ";(I want to extract this part of the object)

thanks!!!!!!!!!

 

<?




$json = '{
    "errorCode": 0, 
    "errorMessage": "", 
    "results": {
        "http://www.n8w.com/image/art/witchcraft/": {
            "hash": "IB0iS", 
            "shortKeywordUrl": "", 
            "shortUrl": "http://bit.ly/e4miJ", 
            "userHash": "e4miJ"
        }
    }, 
    "statusCode": "OK"
}';
$obj = json_decode($json);
print $obj->results['shortUrl']; // 12345

?>

I know whats in the object .. I just can't seem to figure out the syntax to get the variable I need .. it's an object within an object

print $obj->{'errorCode'};

this prints "0"

but what I need is

print $obj->{'results.child.child.shortUrl'}

which should print "http://bit.ly/e4miJ"

json_decode it first.

 

Too fast on keyboard

 

Try $obj->results->shortUrl;

thanks I did .. but I still am not sure how to get

this into a variable http://bit.ly/e4miJ

 

object(stdClass)#1 (4) { ["errorCode"]=> int(0) ["errorMessage"]=> string(0) "" ["results"]=> object(stdClass)#2 (1) { ["http://www.n8w.com/image/art/witchcraft/"]=> object(stdClass)#3 (4) { ["hash"]=> string(5) "IB0iS" ["shortKeywordUrl"]=> string(0) "" ["shortUrl"]=> string(19) "http://bit.ly/e4miJ" ["userHash"]=> string(5) "e4miJ" } } ["statusCode"]=> string(2) "OK" } 

array(4) { ["errorCode"]=> int(0) ["errorMessage"]=> string(0) "" ["results"]=> array(1) { ["http://www.n8w.com/image/art/witchcraft/"]=> array(4) { ["hash"]=> string(5) "IB0iS" ["shortKeywordUrl"]=> string(0) "" ["shortUrl"]=> string(19) "http://bit.ly/e4miJ" ["userHash"]=> string(5) "e4miJ" } } ["statusCode"]=> string(2) "OK" }

results is most likely an array

so

 

print $obj->[results][0]['shortUrl'];

 

NEVERMIND

$json = '{
    "errorCode": 0,
    "errorMessage": "",
    "results": {
        "http://www.n8w.com/image/art/witchcraft/": {
            "hash": "IB0iS",
            "shortKeywordUrl": "",
            "shortUrl": "http://bit.ly/e4miJ",
            "userHash": "e4miJ"
        }
    },
    "statusCode": "OK"
}';
$obj = json_decode($json);
echo $obj->results->{"http://www.n8w.com/image/art/witchcraft/"}->shortUrl . "<br />";
echo "<pre>";
print_r($obj);
die();
?>

 

If you did a dump of the object you would notice that it listed under the actual url:

 

Output from the above:

http://bit.ly/e4miJ

stdClass Object
(
    [errorCode] => 0
    [errorMessage] => 
    [results] => stdClass Object
        (
            [http://www.n8w.com/image/art/witchcraft/] => stdClass Object
                (
                    [hash] => IB0iS
                    [shortKeywordUrl] => 
                    [shortUrl] => http://bit.ly/e4miJ
                    [userHash] => e4miJ
                )

        )

    [statusCode] => OK
)
